“Kill all billionaires” isn’t a genocidal statement, since it’s not based on genetics, language, or culture.
I think it’s a bad plan, but we shouldn’t conflate genocide with mere mass murderous intent. (Also, “all billionaires” is only like 10k people at most, so it would be a very small mass murder compared to most genocides.)
I don’t know about other people, but I tend to drift toward doing things that are fun, comfortable, and familiar, unless I do some “internal parenting”. Even if they found a way to make redistributing their wealth fun, they are shaped by capitalism even more than myself, so I doubt they’d find it comfortable or familiar.
That’s how I understand it.
I’m going to get comfortable and familiar with community investment of my own resources well before I reach 1B, by intention.
